Austen NICE KTM!! and the Ducati!! I have not been on any large 2 stroke Liquid cooled dirt bike like that.. What do you think the HP is?? But I do like my 2 strokes!! I have snowmobiles with 700, 800, 900 cc 2 strokes 165HP. So I know what on the pipe means and it is a rush!! Just take it easy and you will get the feel of the bike. I am sure you have ridden many bikes and some are just an animal to ride and that is what make it feel so good to harness it. Ride safe!! AGAT (All Gear All Time) I guess I need to get my 75 Yamaha RD350 on the road..

Yea, every machine has its problems and characteristics. 18:1 Makes my leg hurt thinking about that. I guess you should use race gas. At least Prem fuel for a easy ride.

I would like to here that pipe 'pop' as you say. I have been to enough races and other shows that have open pipes on 2 strokes. Some motors really have a nice sound. It just make me want to go look at the motor and find out more about it. Now how about a triple 800 2 stroke with megaphones!! That is just plane LOUD. A guy I know has one..

Austen, There is always a reason to put performance parts on. At least that is what I tell my wife. You are probally correct on the Boyesen rad reeds that they will give it more bottom end and smooth out the power band. A little more HP on top end never hurts either!! They need to make Boyesen reeds for our Lawn Boys.. More Power YEA !!

Two Stroke racing

Open class Desert racing.. Some Long Hard days of racing.. I wonder how that guys cylinder cracked?? Did not look like he crashed. Overheated?? 2 strokes lot of work to keep running but a ton of fun!! On the pipe!! Looks like they still race this Finke Desert..
Austen, Never done any dirt bike racing but I love the 2 strokes. Here is a pic of one of my Triple Triples. This one is a 98 Polaris XCR700. This one is sort of old school. 38mm Mikunis, round slide, case reed, High compression. Premium fuel, with the triple tuned pipes. Stock sled. No exhaust valves. It is a pipey machine. When it hits 6500 RPM hang on. It is a rush.. This one has that tin pipey sound also. Some of my others do not. :cool
I am currently working on an older 75 Yamaha GP433 reed valve motor. I looked it up and they still make Boyesen reeds for it. SO my plan is to get it running stock. Get another set of stock reeds, and put the Boyesen reeds on the stock cage. All I see is the carbon pedal reeds for it. Do a back to back comparison.. Should be interesting..

Triples Sound good also. Even the 4 stroke triples. Not many triple lawn mowers. LOL. I have worked on some Toros. Motor in back, deck in front. 3 cylinder gas powered. More of a golf course mower. It could do a backward wheele!! Give me a Kawasaki H1!! I would take an Suzuki GT550 ,I used to ride some.. I need to cool off and go work on my 12 HP single, Lawn Tractor..

Two Stroke Smoke

Thanks for the kind words Austen!! Yea, I like 2 strokes. Sounds like you do to. I like motors of all kinds, but 2 strokes make me smile . Until they break.. If I lived where I could ride from home I might have a few dirt bikes and maybe an open class dirt bike.. Sounds like it would be a rush!! Till it threw me off!! It is enough to have to trailer my sleds to ride. Summer time I have other projects to do and toys to ride.
I forgot to mention that 700 is about 135 HP. Funny you mentioned about power valves. I have 2 other sleds that have power valves. 800 triple and a 600 twin. They are different power bands. They just have a linear pull. Start lower on the RPM and pull good till red line. Get better millage. Probably faster. But they do not have that sound!! Here is a pic of the two triple triples. The red 800 has Flat slide carbs and power valves 155 HP.:2th:
The Tatts Finke Desert Race is in Australia and been going on since 1976. I guess that is why I never heard of it. The Baja 1000 is one we hear more of. The Supercross is in Detroit this weekend. I have not been to one in a long time but the 4 stroke have that low down grunt sound. Not that two stroke sound of yesteryear..
Like you said I could talk about 2 strokes and motors for hours

Good Ride!!

Austen, Great trip you had!! Were you ridding alone? Glad to here your bike worked well and no break downs. Them 2 strokes do get thirsty. Most sleds have about a 10 gallon tank. It is hard to think that snow has so much drag. Wheels roll much easyer. With that 500, no power valve and on the pipe it will suck some fuel. Nice story!! :ThumbUp:
Not much time to post but have been busy working on motors and home projects!!

Sounds like some good upgrades!! I like that Master cylinder!! Some where on line i read the master for the Yamaha RD was on the large size so go to a smaller by a MM or two to get a good feel. I have not got to that one yet.. :tango_face_wink:
